Investigation of thermal residual stresses in tungsten-fiber/bulk metallic glass matrix composites

Insights from the Lattice-Strain Evolution on Deformation Mechanisms in Metallic-Glass-Matrix Composites

“…[40] The residual stress in MGMCs has been extensively reported to be in the range of 100 to 300 MPa for crystalline inclusions and less than 100 MPa in the matrix. [20,[41][42][43][44] For the MGMCs in the current study, there is an initial tensile longitudinal residual stress in the b phase and a compressive stress in the MG matrix, which will slightly affect the initial yield of inclusions in MGMCs, as pointed out in Clausen et al [22] Similar to Clausen et al [22] who used a self-consistent model but not considered residual stress, thermal residual stress is not introduced in our FEMs, but it will be clearly an important future research line.…”

Synthesis and characteristics of 80vol.% tungsten (W) fibre/Zr based metallic glass composite

“…In addition, the interface was thin because of the high volume fraction of tungsten fibres in composite. This was easy to cause residual thermal stress concentration [30] and adiabatic shear behaviour although interface was excellent. Therefore, the interface had a tendency to act as fracture source.…”

Wetting behavior of CuZr-based BMGs/alumina system

“…However, most monolithic BMGs have been proved to fail catastrophically by rapid propagation of localized shear bands during unconstrained deformation at room temperature [8]. To overcome this drawback, BMGs matrix composite reinforced with fibers and particulates have been fabricated by infiltration casting [9][10][11][12] and suction casting [13,14].…”
